DETAILED DESCRIPTION
-
Embodiments of the present invention are described in detail below, examples of which are shown in the drawings. The following embodiments described with reference to the drawing are illustrative. It should be understood that the embodiments described are intended to explain the present invention, but not to limit the present invention.
-
For an air-conditioner indoor unit where an air inlet is located below the air outlet and the air outlet faces forward, an installation height of the air-conditioner indoor unit may be set relatively high, and even a top of the air-conditioner indoor unit may be installed tightly against a ceiling, as long as the air deflector does not interfere with the ceiling during its movement. How to ensure that the air deflector does not interfere with the ceiling during its movement after the installation of the air-conditioner indoor unit is a technical problem that needs to be solved urgently at present.
-
As shown in FIGS. 1 to 5, an air-conditioner indoor unit 100 according to embodiments of the present invention includes a housing 1 and an air deflector 2. The housing 1 has an air inlet 11 and an air outlet 12, and the air outlet 12 is located above the air inlet 11. The air deflector 2 is movably arranged at the air outlet 12 to open or close the air outlet 12. During movement of the air deflector 2, the following condition is satisfied: L*cos c <D, in which, L represents a dimension of a portion of the air deflector 2 located above the housing 1; C represents an included angle between the air deflector 2 and a vertical plane, C is a negative angle in a case that an airflow direction at the air outlet 12 is forward and downward, and C is a positive angle in a case that an airflow direction at the air outlet 12 is forward and upward; and D represents a distance between an upper end of the housing 1 and a ceiling 10 of a house.
-
As shown in FIG. 3, L*cos c is denoted as X, in which X is a dimension of the portion of the air deflector 2 located above the housing 1 in an up-down direction; and D represents a distance between the upper end of the housing 1 and the ceiling 10 after the air-conditioner indoor unit 100 is installed. In the air-conditioner indoor unit 100 according to the embodiments of the present invention, designing L*cos c <D may ensure the air deflector 2 does not interfere with the ceiling 10 during movement of the air deflector 2, thus ensuring normal operation of the air-conditioner indoor unit 100 after installation.
-
In some embodiments, as shown in FIG. 5, the air-conditioner indoor unit 100 further includes a rocker arm 3. The rocker arm 3 is rotatably connected to the housing 1 via a first rotating shaft 31, and the rocker arm 3 is rotatably connected to the air deflector 2 via a second rotating shaft 32. During the rotation of the rocker arm 3, the air deflector 2 is driven to move. Here, it is satisfied that L*cos c=A+R-B. A dashed line denoted as J in FIG. 2 represents a movement trajectory of the second rotating shaft 32, and a rotation angle range of the second rotating shaft 32 represents G.
-
Here, A refers to a distance from an upper end of the air deflector 2 to a horizontal plane passing through a center of the second rotating shaft 32 in a case that the air deflector 2 is parallel to the vertical plane; R refers to a distance between a center of the first rotating shaft 31 and the center of the second rotating shaft 32; B refers to a distance from the upper end of the air deflector 2 to a horizontal plane passing through the center of the first rotating shaft 31 in a case that the second rotating shaft 32 is at a highest position.
-
It may be understood that, as shown in FIG. 5, in a case that the second rotating shaft 32 is at the highest position and the air deflector 2 is parallel to the vertical plane, the dimension of the portion of the air deflector 2 located above the housing 1 is the largest, and the air deflector 2 is most likely to interfere with the ceiling 10. Additionally, in a case that the first rotating shaft 31 is directly below the second rotating shaft 32, that is, in a case that a line connecting the center of the first rotating shaft 31 and the center of the second rotating shaft 32 is parallel to the vertical plane, the distance from the upper end of the air deflector 2 to the horizontal plane passing through the center of the first rotating shaft 31 is a sum of A and R. In a case that the first rotating shaft 31 is below the second rotating shaft 32 and the line connecting the center of the first rotating shaft 31 and the center of the second rotating shaft 32 intersects the vertical plane, the distance from the upper end of the air deflector 2 to the horizontal plane passing through the center of the first rotating shaft 31 is denoted as B. Thus, the sum of A and R is greater than B.
-
Equation L*cos c=A+R-B facilitates obtaining L*cos c , i.e., the value of X in FIG. 2, thereby facilitating the design of the air-conditioner indoor unit 100.
-
It should be noted that during the specific design of the air-conditioner indoor unit 100, parameters R and B need to be designed, while L, C, and A vary with the movement of the air deflector 2.
-
As shown in FIGS. 1, 2, and 4, the air-conditioner indoor unit 100 further includes a fan 4 and a heat exchanger 5. Both the fan 4 and the heat exchanger 5 are located inside the housing 1. During operation of the air-conditioner indoor unit 100, airflow enters the housing 1 through the air inlet 11 under the drive of the fan 4, passes through the heat exchanger 5 and exchanges heat with the heat exchanger 5, and then flows out through the air outlet 12.
-
In some embodiments, the housing 1 includes a front panel 13. The air outlet 12 is located above the front panel 13, and the front panel 13 is arranged to be gradually inclined backward in a direction from top to bottom, i.e., in an up-to-down direction.
-
Arranging the front panel 13 to be gradually inclined backward in a direction from top to bottom allows airflow exiting the air outlet 12 to enter the housing 1 through the air inlet 11 from a lower side of the air outlet 12 in a case that the air-conditioner indoor unit 100 is in a heating mode, thus allowing the airflow entering through the air inlet 11 to have a higher temperature, and also enabling high-temperature sterilization of the heat exchanger 5.
-
Optionally, as shown in FIG. 1, in a case that the air deflector 2 is in a closed state, a front surface of the air deflector 2 and a front surface of the front panel 13 are in the same plane.
-
In a case that the air deflector 2 is in the closed state, the front surface of the air deflector 2 and the front surface of the front panel 13 are in the same plane, so that the air deflector 2 may effectively close the air outlet 12, thus preventing a gap forming at the air outlet 12.
-
Optionally, an included angle between the front panel 13 and the vertical plane ranges from 0 degree to 30 degrees.
-
For example, as shown in FIG. 1, the included angle between the front panel 13 and the vertical plane is denoted a, which ranges from 0 degree to 30 degrees.
-
It may be understood that the larger the included angle between the front panel 13 and the vertical plane, the more hot airflow enters through the air inlet 11, and the better the high-temperature sterilization effect of the heat exchanger 5. However, relatively less hot airflow remained in the room is unfavorable for improving the heating effect of the air-conditioner indoor unit 100. Conversely, the smaller the included angle between the front panel 13 and the vertical plane, the less hot airflow enters through the air inlet 11, and the more hot airflow remains in the room, which is beneficial to improving the heating effect of the air-conditioner indoor unit 100, but the high-temperature sterilization effect of the heat exchanger 5 will be worse.
-
By setting the included angle between the front panel 13 and the vertical plane to 0 degree to 30 degrees, the high-temperature sterilization effect of the heat exchanger 5 may be ensured without affecting the indoor heating effect.
-
In some embodiments, D is greater than 0.
-
D being greater than 0 ensures that after the air-conditioner indoor unit 100 is installed, the distance between the upper end of the housing 1 and the ceiling 10 is greater than 0, i.e., there is a gap between the upper end of the housing 1 and the ceiling 10. This allows the distance between the upper end of the housing 1 and the ceiling 10 to be larger, thus more effectively preventing interference between the air deflector 2 and the ceiling 10 during the movement of the air deflector 2.
-
Optionally, D is greater than or equal to 30 mm.
-
D being greater than or equal to 30 mm ensures that after the air-conditioner indoor unit 100 is installed, the distance between the upper end of the housing 1 and the ceiling 10 is greater than or equal to 30 mm. This allows the gap between the upper end of the housing 1 and the ceiling 10 to be larger, thus more effectively preventing interference between the air deflector 2 and the ceiling 10 during the movement of the air deflector 2. Additionally, during the installation of the air-conditioner indoor unit 100, it may be moved slightly in the up-down direction to facilitate the installation and fixation of the air-conditioner indoor unit 100.
-
In some embodiments, as shown in FIG. 2, in a case that the air-conditioner indoor unit 100 is in the heating mode, C is a negative angel or zero, and an airflow direction at the air outlet 12 is forward and downward. In a case that the air-conditioner indoor unit 100 is in a cooling mode, C is a positive angel, and an airflow direction at the air outlet 12 is forward and upward.
-
In a case that the air-conditioner indoor unit 100 is in the heating mode, the airflow direction at the air outlet 12 is forward and downward, which may increase a landing speed of the airflow exiting from the air outlet 12, thus improving the heating effect of the air-conditioner indoor unit 100. In a case that the air-conditioner indoor unit 100 is in the cooling mode, the airflow direction at the air outlet 12 is forward and upward, which may reduce a vortex generated by the airflow exiting from the air outlet 12, thus preventing condensation caused by the air-conditioner indoor unit 100.
-
Optionally, A ranges from 50 mm to 80 mm. For example, A is 63.27 mm.
-
As shown in FIG. 4, in a case that the air deflector 2 is parallel to the vertical plane, the distance A from the upper end of the air deflector 2 to the horizontal plane passing through the center of the second rotating shaft 32 is the largest.
-
Setting A to range from 50 mm to 80 mm may effectively prevent the air deflector 2 from interfering with the ceiling 10 during movement of the air deflector 2.
-
Optionally, R ranges from 85 mm to 95 mm. For example, R is 90.1 mm.
-
Setting R to range from 85 mm to 95 mm may effectively prevent the air deflector 2 from interfering with the ceiling 10 during movement.
-
Optionally, B ranges from140 mm to 160 mm. For example, B is 148.09 mm.
-
In a case that the second rotating shaft 32 moves to the highest position, the distance B from the upper end of the air deflector 2 to the horizontal plane passing through the center of the first rotating shaft 31 is the largest.
-
Setting B to range from 140 mm to 160 mm may effectively prevent the air deflector 2 from interfering with the ceiling 10 during movement of the air deflector 2.
-
Optionally, a width of the air deflector 2 ranges from 88 mm to 124 mm.
-
For example, as shown in FIG. 2, the width of the air deflector 2 is K, and K ranges from 88 mm to 124 mm.
-
Setting the width of the air deflector 2 to range from 88 mm to 124 mm may ensure that the air deflector 2 effectively closes the air outlet 12, and allow the air-conditioner indoor unit 100 to achieve good airflow effects in different operating modes.
